Title: Method of delivering disinfectant in an absorbent substrate
Inventor: CODE KENNETH REAY
IPC: A61L15/44
Filed: 1997-04-04
Abstract: A method of delivering disinfectant in an absorbent substrate.  A first step involves intermixing a first reactant chemical with a first ink.  A second step involves intermixing a second reactant chemical with a second ink.  A third step involves printing a first pattern on an absorbent substrate with the first ink.  A fourth step involves printing a second pattern on the absorbent substrate with the second ink.  The second pattern is positioned in close proximity to the first pattern, such that when the first pattern and second pattern are exposed to water an intermixing of the first reactant chemical and the second reactant chemical occurs to produce an aerosol disinfectant.

Title: Photothermographic element with reduced woodgrain interference patterns
Inventor: STEWART DARLENE F
IPC: G03C1/498
Filed: 1995-10-05
Abstract: The present invention provides a spectrally sensitized photothermographic silver halide element comprising a support layer having on at least one surface thereof a photothermographic composition which displays uniform image density across its surface when exposed to floodlight or uniform incandescent light exposure at radiation wavelengths to which the element is sensitive, said element comprising at least two layers, including a top layer and a photothermographic emulsion layer, said photothermographic emulsion layer comprising a binder, a light insensitive silver source, a reducing agent for silver ion and infrared radiation sensitive silver halide grains, wherein the coherent radiation is rendered more diffuse in its passage through the element than when it strikes the top layer. This may be accomplished at least in part by 1) the top layer of the element having haze induced therein of 0.05 to 30 %  by surface modification of that layer, 2) there being a random refractive pattern on the top layer, 3) haze being induced in the silver halide containing layer, 4) the reflective characteristics of a surface of the support layer facing the photothermographic composition have been altered to reduce reflection of coherent radiation into said composition, and/or 5) having a radiation absorbing material contained within the photothermographic element to decrease light reflected off of the support.

Patent CA-2206038-A1 (CA)
Title: Air diffuser apparatus
Inventor: FELSEN KARL H
IPC: F24F13/06
Filed: 1997-05-23
Abstract: An air diffuser apparatus has a box-like air diffuser chamber with sheet metal side walls, that are provided with a series of laterally spaced outlet orifices. Each orifice is formed by cutting out wing portions of the sheet metal on each side of a center line of the orifice and bending the wing portions outwardly to a position inclining toward this center line.  The wing portions define an air flow passage tapering in an outward direction.  The chamber has a base connected to a lower edge of the side walls that includes a layer of heat insulation material.  An upper structure closes the upper end of the chamber and has an inlet opening for introducing pressurized low temperature air into the chamber.  This arrangement is highly efficient for diffusion of low temperature air and can be of essentially all-metal construction and is economical and durable.

IPC: B60P1/43
Filed: 1997-10-31
Abstract: A foldable ramp having a first, second and third rectangular sections contiguous with each other and defining a ramp path having longitudinal and transverse axes. A first hinge group is affixed to both the first and second sections and a second hinge group is affixed to both the second and third sections. The first hinge group has a first axis of rotation on the upper side of the ramp path and extending across the longitudinal axis, and a first rotational range of slightly more than 180°. The second hinge group has a second axis of rotation on the under side of the ramp path and extending in a parallel alignment with the first axis of rotation, and a second rotational range of slightly less than 180°. The first and second hinge groups each have a central hinge and outside hinges, and stoppers on the central hinges to limit the rotation of the central hinges a few degrees less that the rotational range of the outside hinges. This configuration causes the ramp to arc longitudinally and transversely upwardly when deployed for increasing the moments of inertia of the ramp.

Title: Grille-pain a fermeture reduisant la consommation d'energie
Inventor: YEUNG MIU-CHOY
IPC: A47J37/08
Filed: 1996-09-11
Abstract: L'invention concerne un grille-pain possédant une fermeture mécanique pour chacun de ses compartiments, s'il en a plusieurs. La fermeture recouvre au moins en partie la fente de son compartiment en cours de fonctionnement, ce qui a pour effet de réduire le transfert de chaleur (essentiellement dû à la convexion) depuis le grille-pain lui-même et l'article en cours de grillage. Dans certains modes de réalisation préférés, ladite fermeture se présente sous la forme d'une paire de plaques coulissantes (14, 15). Lorsqu'un chariot (8) (sur lequel est placé l'article destiné à être grillé) est abaissé manuellement par l'utilisateur, une liaison mécanique (2, 7) partant du chariot fait coulisser les plaques conjointement afin de couvrir (sensiblement ou totalement) une fente de compartiment. Lorsque le chariot se relève brusquement (en fin de grillage), la liaison mécanique (2, 7) fait écarter les plaques l'une de l'autre pour permettre le retrait de l'article grillé.

IPC: C23C2/00
Filed: 1998-03-30
Abstract: A printing station conveys a supply of molten lithium from a heated tank to a nozzle within a protective shroud. A web traverses a chiller also within the shroud. The nozzle dispenses discrete amounts of the molten lithium onto successive portions of the web in contact with the chiller.  The chilled lithium solidifies into solid lithium patterns.  A sealer also within the shroud prevents exposure of the solid lithium patterns to ambient air. The station can be incorporated into an in-line press for forming a succession of electrochemical cells.

Patent CA-2235231-A1 (CA)
Inventor: LOCKHART THOMAS W
IPC: H04W28/12
Filed: 1998-04-17
Abstract: System and software method of operation of a radio data base station (RDBS). Two RDBS (12 and 14) individually transmits and receives signals on a common frequency. A wireless terminal (10) transmits a packet having at least a station identifier signal (56) identifying a RDBS. The packet is received at both RDBSs (12 and 14). Both RDBSs detect a beginning portion of the packet, set a busy bit and transmit a busy signal. Both RDBSs (12 and 14) determine whether the beginning portion has a signal strength greater than a threshold. If the beginning portion is less than the threshold, the RDBS clears the busy signal. If the beginning portion is greater than the threshold, the RDBS decodes the station identifier signal (56). If the station identifier signal (56) does not identify the RDBS, the RDBS clears the busy signal previously set. If the station identifier signal (56) identifies the RDBS, the RDBS continues to transmit the busy signal until the entire packet is received.
